Prevalence of Chlamydia trachomatis infection in Samoan women aged 18 to 29 and assessment of possible risk factors: a community-based study.

BACKGROUND: Knowledge about genital Chlamydia trachomatis (CT) infections in the Pacific is limited. In this study we investigated CT infection in Samoan women. METHODS: We recruited women having unprotected sex aged 18 to 29 years from 41 Samoan villages. They completed a questionnaire and provided a urine sample for CT testing by PCR. Associations between CT infection and possible risk factors were explored using logistic regression. RESULTS: Altogether, 239 women were recruited; 86 (36.0%; weighted estimate of prevalence: 41.9%; 95% CI: 33.4-50.5%) were positive for CT infection. A higher proportion of women aged 18 to 24 were positive (54/145; 37.2%) than those aged 25 to 29 (32/94; 34.0%; p=0.20). Being single (OR 1.92; 95% CI: 1.02-3.63) and having two or more lifetime sexual partners (OR 3.02; 95% CI: 1.19-7.67) were associated with CT infection; 27.6% of those with one lifetime partner were positive. Participants who had a previous pregnancy were less likely to be positive (OR 0.49; 95% CI: 0.27-0.87). Primiparous and multiparous women were less likely to be positive than nulliparous women (OR 0.54; 95% CI: 0.30-0.99 and OR 0.46; 95% CI: 0.24-0.89, respectively). CONCLUSIONS: The prevalence of CT infection in these Samoan women is very high. Further studies, including investigating the prevalence of CT infection in men, and strategies for sustainable control are needed.

Strengthening health research capacity from within Samoa.

This article reflects on the challenges of strengthening health research capacity from within Samoa. It examines the status of health research and related curricula in Samoa and discusses the outcomes of a new postgraduate applied social and health research methods course taught in Samoa for the first time from 5 January to 12 February 2010 by the Department of Preventive and Social Medicine, University of Otago in collaboration with the Centre for Samoan Studies, National University of Samoa. The article argues that collaborative health research courses such as this methods paper can fill a curriculum gap in New Zealand and Samoa and contribute directly toward strengthening Samoa health research capacity in ways that benefit both Samoa and New Zealand. This initiative can be a flagship for strategies operating from within Samoa that can build real win-win type partnerships. These can be ably led by Samoans for the ultimate development of an affordable and sustainable quality health and education infrastructure for Samoa.
